2005 PCM failure at 36K - warranty covered?

A quick search just revealed that this is a rare failure, but it's what the local dealer diagnosed after a total flameout/shutdown on city streets last week.

My first thought was a fuel pump failure, but the knowledgable tow truck driver noticed the MIL flashing during cranking. It was a serious failure. While waiting for the tow, I checked all the fuses and was very relieved that I was not out in the rugged AZ wilderness with this fatal problem.

Some background is that my MIL illuminated a few times earlier this year with a code indicating the fuel evap system. I've no idea if related, but it's in the history of an otherwise good-running and reliable TJ.

The good news? Service advisor sez its warranty covered (wife took the message), but honestly I'm afraid to even call him to discuss why they're covering. I'll wait for the pickup call; est one week. They do not stock these parts. He said I'm liable for only the $80 initial diagnostic fee.

I'm advised that all vehicles must appropriately maintain their emissions systems well after (50K miles?) the slim factory warranty. Or perhaps, being slightly under 36K (but six years old), they are just being nice to me (huh?). I'm still scared to go pick up the girl when they call me. PCM/ECUs cost well over $1K, I know having a '98 GC with a failure a few years ago.

Anyone know the actual factory rules?

I'll repost the actual results when they happen in the next few days.

Again, feeling so lucky it happened in town, rather than jammed between rocks in the middle of nowhere.

If it is covered under the 8/80 emissions warranty, the diagnostic charge should be too.

Yes, dealer did replace PCM computer and cover the diagnostics under warranty. Failure mode was an "internal short". Zero dollars. Only cost to me was not driving it for a week....so, a net savings!

Of course, they tried to sell me about $500 worth of decarboning and tuning, I'll take care of that myself. Not surprisingly, she runs exactly the same as before.

My mechanic is talking to the local Jeep dealership to find out if it's covered under the 80K emissions warranty. Crossing my fingers that it is covered.
